Power Train 15 1 crash 1 injury

“On the morning of October 25, 2021 at approximately 7:05 am, I was fixing to leave to go to work. The carport light was on, so I open the door to my car, slid into the driver’s seat, started the car up and the lights came on. As I was starting to get out of the car to go turn the carport lights off, I realized the car was going backwards. I tried to get back into the driver’s seat to try to stop the car but I was unable to do so. The door knocked me down on the concrete floor of the carport and the front left tire ran over both my legs. The car continued to go backwards, the door hit the…”

“Start/stop function malfunctioned in the middle of the road, this has happened multiple times before and after replacing starter and battery, looked at by several mechanics.

They first appeared a few months ago and I had already gotten work done on it and it…”

“Evaporative emission canister purge, solenoid valve, yes. My safety was at risk due to stalling 3 different times on busy roads/intersections after refueling my vehicle. When the Solenoid valve and canister fail when coming to a stop after refueling it causes the car/engine to flutter and completely stall then goes into neutral. It takes multiple restarts in order to even make the car go along with pressing on the gas. This part has been replaced twice by the dealership once at the end of march and again on the 10th of June. The first incident occurred mid-march, the second end of march and…”
